PAPER VESSEL.

Speecation of Letters Patent.y Patented Sept. 2S, 1909.

' Application led December 5, 1908. Serial No. 466,146.

Be it known that I, CHARLES FRANCIS JENKINS, a citizen of .the UnitedStates,

residing at Washington, in the District of Columbia, l1ave..inventedcertain new and useful Improvements in Paper Vessels; and I' do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My presentinvention relates to closures for paper vessels, and has forits object the provision of a closure whichwill be easily applied by theordinary bottle filling and capping machines-now in use; one which willbe efiicient'in action and cheap to construct; and one which will, whenthe closure is applied to milk bottles, permit the housewife to readilyseparate lthecream froml the milk.

To these ends the invention consists in the details ofconstruction andnovel combina- .shown in Fig. 3.

tion of parts more fully hereinafter disclosed, and particularly pointedout in. the claims. y

Referring to the accompanying drawings forming a part of thisspecification, in which like numerals refer to like parts in all theviews:-Figure 1, is a. longitudinal sectional View ofa paper vessel withmy closure applied thereto. Fig. 2, a similar view showing a modifiedconstruction of closure. r Figs. 3, 4 and4 5, represent in section stillother modifications of the closure; while Fig. 6, represents inperspective the parts of the closure shown in Fig. 3, before they areassembled. Fig. 7, is a plan View of the top disk of the closure shownin Fig. 1. Fig. 8, a like view of the topl disk shown in Fig. 2, andFig. 9a planview of the top disk 1 represents any suitable paper vessel,but preferably a spirally wound paper milk bot tle; 2 an invertedcup-shaped bottom closure, and 3 a large plug like or thickened disklike, top closure. The top closure 3 in all cases comprises an invertedcup 4, having the struck up flanges 5, from which may or may not projectone or more ears or tabs 6,

as maybe desired, but in most cases a single tab will be foundsuflicient and desirable to Withdraw the closure. Fitting into this cup4, is a filling block of solid material, which' in lFigfl, is shown asmade up of a plurality of fiat pieces 7, which may be disks of paper; inFigs. 2Vand 5, as made up of a plurality of blocks 8, which may bepapel'- board or othermaterial; while in Figs. 3 and the filling block 9is a solid piece of paper-board, wood or other material. Fit` ting overthis filling block in Figs. l and 3, is a disk 10 preferably of paper;and this disk in Fig. 1, is or may be provided with notches 11, as shownin Fig. v7, to accommodate the two ears or tabs 6 of the cup 4.

Fig. 8 shows -a single notch 12 in the edge of the disk 15 toaccommodate the single tab 6 shown in Fig. 2; and Fig. 9 shows fournotches 13 to accommodate the four tabs belonging to the cup 4 shown inFig. 3. The disk 15 of Figs. 2 and 8, is provided with a circular groove16 to receive the edge which fits over and receives the top edge ofthe'cup 4. In this figure, as well as in Fig. 5, the notches aredispensed with; and in the latter figure the continuous smooth edge ofthe disk 19 jams down the' ears or tabs 6, as shown, causing them to litagainst the upper ledge of the bottle 1, in the manner similarto that ofthe grooved flange 18 in Fig. 4.

In all the figures an inverted cup `of liquid proof material is providedwhich furnishes a continuous surface, and prevents liquid getting intothe stopper to swell the same; a solid thickened disk like or flattenedplug like stopper is provided which is readily vhandled by the cappingand iilling machines now on the market; when this stopper is withdrawnthe opening is suflicient for the house`-wife to readily skim ofi.l thecream; and the whole structure can be readily made from the waste paperproduced by my bottle making machines. The tabs enable one to readilywithdraw the stopper, although it is jammed down flush with the top edgeof the bottle; and when the said stopper is so made Hush with the saidtop the bottle presents a smooth top, which is considered very desirableby the boards of health of the various cities, in order to prevent dirtand germs collecting thereon and thereby spreading disease.

What I claim is z- 1. A paper vessel closed at one end with a flangedcup and provided at its other end With a plug stopper comprising aflanged cup having a tab integral With the flange, and extending inprolongation of the same; a filling material solidly fitting said cup;and a disk overlying said filling material, having a notch fitting saidtab, substantially as described.

2. A paper vessel closed at one `end With an inverted flanged cup; andhaving at its other end'a plug stopper Comprising -a flanged cupprovided With a tab, a filling material composed of a plurality ofpieces solidly fitting the same and a notched disk fitting the tab andoverlying the filling material, substantially as described.

3. A paper vessel closed at one end With an inverted flanged cup; andhaving at its other end a plug stopper eomprising a flanged cup providedwith a tab, a filling material composed of a plurality of flat diskssolidly fitting the same, and a disk over said filling material providedwith .a notch fitting said tab, substantially as described.

4. A spirally Woundpaper vessel closed at one end with an invertedflanged cup; and provided with a plug stopper composed of a flanged cupof liquid proof material having a tab integral With the flange; aplurality of layers of material solidly fitting said cup; and a notcheddisk fitting said flange and covering said layers, substantially asdescribed.

In testimony whereof, I aflix my signature, in presence of tWoWitnesses.
